Beyond above adaptations, the latest series "zstd-v5" of Nick T.s patchset needs some addition of zstd to the patch (see [1]): commit 8dfb61dcbaceb19a5ded5e9c9dcf8d05acc32294 "kbuild: add variables for compression tools" NOTE: "zstd-v5" was against Linux-next 20200408 or download the series from patchwork LKML which applies cleanly against Linux v5.7 - last is what I did. There was a follow-up to the above patch (see [2]): commit e4a42c82e943b97ce124539fcd7a47445b43fa0d "kbuild: fix broken builds because of GZIP,BZIP2,LZOP variables" Nevertheless, this is the kernel-side of doing - user-space like for example Debian's initramfs-tools needs adaptations (see [3]). @Kees: Can you aid Nick T. to get this upstream? You know the processes a bit better than me.
